Fig. 6 isa View of the air-vent tube as seen in centrallongitudinal section. Fig. 7 is a view in elevation (on a reduced scale) of a keg containing the liquid, which is to be dispensed by sald apparatus. Figs. 2, 3, 4, 5 and-'6 are on a larger scale than Fig. 1, and Fig. 7 is on a reduced scale.

My invention relates to apparatus for dispensing gas-impregnated liquids, such as soda-water, beer, and other beverages; and

it consists of the novel construction and,

combination of the several parts or elements as hereinafter described and set forth in the claims.

In the drawings, 1 represents the exterior portion or case, which is provided with a.

detachable cover 2. A lurality of tanks rest upon a support 3 Within the case and extend, vertically. Any desired number of such tanks may be used.' I show in the drawing two tanks, designated as 4- and 5,

respectively. Beneath this case is a keg or other receptacle containing the gas-impregnated liquid, or other liquid under pres- 1. The pipe 6 is supported at the place where i it enters the case 1 by means of the collars 8- and 9 in contact with the bottom of the case, as seen in Fig. 1.- The pipe 6 is bent as shown at 10 and 11 and passes into the tank 4 at the top thereof. The end of this pipe, in the portion of it which is within the upper part of the tank 4, is spirally bent, as shown at 12, and is thcreprovided with a plurality of discharging orifices 13 directed radially upward. The flow of the liquid through. this pipe is indicated by the arrows 7, 14, 15, 16 and 17.

A pipe 18 has an open end at its bottom near the bottom of the tank 4, and is curved so as to pass out of said tank through the side thereof, as represented in Fig. 1. Said pipe has an annular flange 19, as seen in and 22 are equal, so that said two pipes 18 and 22 are continuous with eachother. A valve seat 23, annular and beveled as illustrated in Fig. 2, is made. The opposite 'end of the pipe 22 has an interior-screw-tliread and is enlarged to form an annular flange 24. An upright pipe or T 25 opens into the pipe 22-, as shown, and has an exter1or screwthread The bore of the pipe 22 between the valve seat and the flanged end 24 of said pipe is of a slightly enlarged diameter for the movement of a valve therethrough, as presently explained. Avertical pipe 26 1s connected to the T-branch or pipe 25 by a union 27. The pipe 26 has the bends 28 and 29, and passes through the upper end of the tank 5, and is formed with a splral curve in the upper part of the tank'5 as appears at 30. The spirally bent end of the pipe 26 Within the tank 5 is provided with a plurality of discharging OIlfiCQS 31. The flow of the liquid through the pipes 18, 22, 25, 26 and 30 is indicated by the arrows 31 32, 33, 34, 35, 36, 37 and 38.

A- discharging pipe 39 has its open end located near the bottom of the tank 5. Sa1d pipe 39 is curved so as to pass out from the ling 41.

head or casting 42 has a cylindrical portion, which is provided with an exterior screw-thread 43, and also has an annular flange 44, adapted to he in contact with the case 1 011 the inner surface thereof. The

.head 42 also has a rearwardly-directed A straight bore extends through the head 42 y from front to rear, and is continuous with the bores of the tubular extensions 45 and 46. This bore is enlarged diametrically, as shown at 47 in Fig. 2.

' The head 42 has near its outer end a downwardly extending discharge pipe or nozzle 48, which has a tapering axial bore 49, continuous with an L-shaped bore 50, which passes through the head 42, as shown in Fig. 2. This L-shaped bore is concentrically enlarged and screw-threaded to receive and engage the end of the pipe 40, which enters the head 42, as illustrated in Fig. 2.

The nozzle 48 has a tubular valve 51, extending therefrom at right angles, and made with a tapering bore. valve 52 is rotatably mounted in the valve tube /or case 51, and has a diametrical aperture 53, so that when the plug 52 is turned, said aperture registers with the bore of the nozzle 48, as seen in Fig. 2. The plug 52.

has at its smaller end a concentric stem or projection 54, of smaller diameter and which is cylindrical and screw-threaded. A washer or packing 55 is mounted on the projection or stem 54, and a check nut 56 is in threaded engagement with said projection. The outer end of the plug 52 has a concentric stem or projection 57, of smaller diameter and cylindrical in shape. A collar or binding nut 58, having a screw-threaded bore engages the exterior screw-threads 43 of the head 42, and can thereby be brought intotight contact with the exterior surface of the case 1. A valve 59, shaped as a circular disk with a beveled edge, adapted to fit in the valve seat 23, is supported upon the inner end of a valve stem 60. The valve stem 60 has a spiral groove 60* along which it is movable b its engagement with the stud pin 60 of t e straight bore of the head 42. A screwcap or stuffing box 61 has a central tubular bore, through which the outer end of the valve stem 60 passes loosely, and said cap is mounted upon the threaded surface of the forward extension 46 of the head 42.

1A'hand wheel 62 has a hub 63, with a bore adapted to receive the extreme outer end 64 of the valve stem 60, the latter being provided with angularly-disposed longitudinal faces fitting in said bore which has similar A conical plug or surfaces to engage therewith. The wheel 62 also has on its rear surface a tubular boss 65. The outer end 57 of the plug 52 is provided with bent arm or crank 66, having a tubular end. A link bar 67 is pivotally connected with the tubular boss 65 of the wheel 62 by a screw 68, and with the tubular end of the crank 66 of the plug 52 by a screw 69.

A vent tube. 70 extends through the top of the tank 4, as seen in Fig. 1, and projects out from the case 1. It is furnished with an exterior screw-thread. A tubular head or cap 71, having an interior screw-thread, is rota tably mounted on the tube 70 and has an air-. admission aperture or opening 72, seen in Fig. 6. In each tank (4 or 5) a vertical rod 7 3 is placed, resting loosely upon the bottom of the tank. On each rod 73 a plurality of slitted circular baflling disks 74, and 7 5, are placed, preferably in sets of two each, said sets being equi-spaced upon the rod 73, and extending into contact with the interior cylindrical surface of the tank 4. Each upper battling disk 74 rests loosely upon a washer or collar 76 which surrounds the rod 73 and said washer or collar rests loosely upon the top surface of the lower baffling disk 75. The lower battling disk 75 .rests loosely upon a tube 77. The lowest tube of the series may be fastened or secured to the rod 73 by cross pin, or in any other suitable manner. The baffling disks 74, 75, are made of sheet metal preferably about 1 g of an inch thick, and the slits are preferably about g of an inch in width. The washers or collars 76 are preferably about of an inch thick. The bafiling disks 74, 75, bf each set are so arranged upon the rod 73 that the bars 78 of the bafliing disk 74 are at right angles with the bars 79 of the battling disk 75.

In Fig. 7 is represented a keg 89, into which the pipe'6 extends. In the pipe 6 is a valve 87, allowing the liquid to flow up from the keg 89 through the pipe 6 into the tank 4.

The operation of my improved dispensing apparatus is as follows. The valve 87 being turned, the liquid contents of the keg flow up (by the pressure of the gas therein contained and diffused) through the pipes 6 and 12 into the tank 4; thence through the pipes 18, 22, 25 26 30-into the tank 5; thence through the pipes 39 and 40, bore 50 and nozzle 48 into the tumbler 82, whenever the various valves are in proper position for that purpose. The liquid, when first discharged which is delivered from the nozzle 48.

IVhenever by a quarter-rotation of the wheel or handle (32, the valve stem (30 is moved to withdraw the valve 59 from the valve seat 23, the liquid in the tank 4, still under gaspressure, flows through the pipes 18, 25, and 2.6, and is discharged again in like manner from the discharging orifices 31 of the spirally curved end 30 of the pipe 26 into the tank 5,. whence it descends through the slitted battling disks. to the bottom of the tank 5 and so fills the same. The quarterrotation of the Wheel (32 not only unseats the valve 59, but at the same time and to the same extent turns the plug 52 and causes the valve aperture 53 to register with the bore 50. This simultaneous valve-operation is caused by the cccentrically-located boss ()5 (moving with the wheel 62) and compelling the link bar 67 to turn the crank 66 of the plug 52. Thus the beer or other gas-impreg nated liquid is served in a lively, effervescent condition under the natural head (if a fermented liquor) or under the original gas' pressure (if a carbonated liquid). It has been common heretofore to dispense a beer or other beverage in a flat, stale condition, due to the fact that the gas hasbubbled off and escaped, and then to top off the beverage in the tumbler with foam by drawing the gas or mingled gas and liquid from another source to enliven the flat, stale mass of liquid constituting the bulk of the draft; but such foam or gassy liquid from another source cannot mix with the denser body of liquid first drawn nor penetrate it to any considerable degree. By my apparatus, as already explained, it is seen that the liquid dispensed is thoroughly and evenly impregnated with the original head or pressure of the beverage before the gas has-escaped or bubbled off to any harmful degree.

As shown in Fig. 1, the case 1 is filled with broken ice, which chills the tanks 4, 5, and the pipes 6, 26 and 39, and cools the liquid Any desired number of tanks may be used in this construction. If desired, the discharging orifices 13, 31, may be directed downward to deliver the liquid directly upon the uppermost of the bafliing disks 74, and said baffling disks, instead of contacting directly with the inner surfaces of the tanks 4' or 5,

may be separated therefrom by a small In order that the bathing disks and interior portions of the tanks can be cleaned, which is very important, especially if a fermented liquid, instead of a carbonated liquid, is dispensed, provision is made for removing said batliing disks and their supporting-rod from the tanks. For this purpose the top of each of the tanks at and 5 should be a detachable cover, as shown at and 5-1, respectively, secured to the body of the tank by a screw thread, or in any other suitable manner. The vent pipe 70 has a coupling 82; the pipe (3 has a coupling 83; and the pipe 26 has a coupling 84. Thus the screw cap or cover 80 can be detached from the tank 4t and the pipes 70 and 6,.and the screw cap or cover 81 can be detached from the tank 5. When the cap or cover 80 has-been removed from the tank 4, the rod 73 with the battling disks 74, 75, thereon can be taken from the tank 4:; and when the cap or cover 81 has been removed from the tank 5,. the battling disks and supporting rod therein can be taken from the tank 5. The bottom of the rod 7 3 is rounded and rests loosely onthe bottom of the tank and: therefore is easily lifted out of position.
